I would suggest to submit a PR, makes sense.

WIll have a look soon-ish. Not 100% sure it really comes from this commit, if I comment the whole FreeBSD block the test still fail the same way.

for the time being, need to add those constants as exception (for CI), as if musl then ignore those two.

nice, it might be best to create a PR for this musl update alone tough. cc @tgross35

You re in the luck, seems [it is already there](https://github.com/rust-lang/libc/blob/libc-0.2/src/unix/bsd/netbsdlike/mod.rs#L504).
